Abstract: Power electronics technology is one of the major innovation players in modern power distribution grids. Power electronics systems are at present deeply penetrated in low-voltage grids. Recently, their importance is significantly growing also in medium-voltage and high-voltage power grids. The power electronics technology brings new solutions and features for power routing (including interfaces to renewable and distributed power sources and energy storage systems), power quality (reactive power compensation, voltage conditioners, active power filters), safety and protection systems as well as grid diagnostics. This keynote will pay the main attention to a new power electronics technology for earth fault solution in high-impedance grounded or insulated medium-voltage power distribution grids. The invented technology behaves like a controlled current source which can be connected either between the distribution transformer neutral point and ground (where it can replace the conventional arc suppression coil used in the grids for more than 100 years) or between the phase conductors and ground. Under the earth fault, the new device can compensate fundamental component of both reactive and active fault current. It can also compensate higher harmonics of fault current. Under fault-free grid operation, the device can compensate grid non-symmetry and the version connected to the phase conductors can compensate grid reactive power and/or grid harmonics. Moreover, the invented technology can be also used for grid impedance identification, faulty feeder detection and exact fault localization. This technology brings to the grid operators many other benefits and new features that will be presented. A prototype of 22 kV / 1.35 MVA has been developed and tested in medium-voltage power electronics labs in R&D center RICE. The prototype has been successfully tested under real distribution grid conditions at a substation 110/22 kV. The experience from one year operation of this technology in the grid and future research challenges will be presented.

Abstract: The fast development of distributed generation systems (DGS), including increasing number of the renewable energy sources (RES) demand the change of classical grid into smart grids (SG) integrating all new distributed elements e.g. active loads/sources/energy storages. Currently used conventional transformer cannot fulfil all requirements of SG and therefore new solution is demanded due to the nature of extremely different types of energy sources, loads and frequent voltage disturbances occurring in DGS. The proposed modern solution is the application of multifunctional power electronics fault tolerant Smart Transformer (ST) that is able to not only meet main requirements of SG, but also respond to the future challenges, defined by the constant progress of technology in all new fields (e.g. electromobility, energy store systems etc.).

Abstract: DC grids are considered to be a key technology for the connection, collection and integration of renewable energy resources, for the realization of integrated power systems, for mobile applications (electric ships, aircrafts), for new types of urban and industrial distribution power networks and to bridge and support existing AC systems. Advanced power electronic components, power converters and system protection are enabling DC grids on multiple voltages levels. Especially medium voltage DC grids are expected to play a key role in managing the higher power flows in our future distribution grids. Roadmap for DC and different steps and research at the TUD is presented with focus on DC grids and DC microgrids. Problem of Power Flow control in DC grids is addressed first an Power flow controller introduced. A zonal protection framework where the low voltage dc grid is partitioned according to short-circuit potential and provided degree of protection, and several known protection schemes that ensure selectivity, sensitivity and security will be discussed.
